目的:了解I期煤工尘肺患者肺功能损伤特点及影响因素,对I期煤工尘肺患者提出相关的防治措施。方法:用日本产HI-38肺功能测定仪对重庆某煤矿357例I期煤工尘肺患者进行肺功能测定并分析肺功能和各影响因素之间的关系。结果:煤工尘肺患者FVC、FEV1.0、FEV1/FVC%实测值与预测值的比值分别为76.8%、54.6%、58.1%,肺功能明显降低(P<0.05)。分析肺功能各项指标及肺功能损伤与工龄、患龄、工种、吸烟之间的关系,表明肺功能降低和损伤严重程度与工种、吸烟密切相关。结论:应加强对煤矿工人的劳动保护,提倡不吸烟的健康方式。
Objective: To understand the characteristics and influencing factors of pulmonary function impairment in coal miners with stage I pneumoconiosis, and to provide relevant prevention and treatment measures for patients with stage I pneumoconiosis. Methods: The lung function of 357 coal miners with stage I pneumoconiosis in a mine in Chongqing was determined by HI-38 pulmonary function test instrument and the relationship between pulmonary function and various influencing factors was analyzed. Results: The ratio of the measured value of FVC, FEV1.0 and FEV1 / FVC% of coal workers with pneumoconiosis was 76.8%, 54.6% and 58.1%, respectively. The pulmonary function was significantly decreased (P <0.05). Analysis of various indicators of lung function and lung function impairment and length of service, age, type of work, smoking, the relationship between that lower lung function and severity of injury and work, smoking are closely related. Conclusion: The labor protection of coal miners should be strengthened and the non-smoking health promotion should be advocated.
